To all 'whom it may concern: .p

Beit known-.that l, EDWARD B. Huss, a citizen ,of the United States of America, residing lin .the borough of'. Brooklyn, cityI and State 'of Newl York, have invented. certain. Improvements in T' e-Writing Machines, of which theiollowing 1s a specification.

This invention-relates to im rovements in whereby'a varia le, throw may'be imparted tothe rlbbonvibrator tocar-ry different Vzones of the rbbonto' the. printing oint.. l

'lheinventionv` is particular y designed for use with aribbonV having pluralzones of'unlike character or color from either of which, at the willof the operator, printing may be effected." i

The'primary' feature ,ot the invention con-v sis'tsin the employment of apart, s uch as'a respectively, by means under control ofthe operator, brought into the'path of the universal bar which latter may have a uniform range of depression as is commonly the case in typewriting machines. The movable block is connected byappropriatev devices with the `ribbon guide or vibrator the extent of movement of which when the key 'levers are operated will de end. upon which one of the surfaces of the b ock is acted upon by the universal bar. v

In the accom anying drawings: Figure 1 is a longitudina vertical section showing so much of amachine as is deemed desirable to illustrate the invention Fig.'2, an .enlarged detail section showing the ribbon vibrator and the escapement devices: Fig. 3, a front elevation of some of the parts shown in Fig. 2: Fig.- 4, a front elevation of the machine artly broken away: Figs. 5, 6 and 7 are enarged detail views showing respectively the adjustment for printing from the bottom of a ribbon, from the top thereof and for stencil work! Figs. 8, 9 and 10 are detail views showing eccentric adjustments: Fig. 11, a

maybe operated. in

cis the ribbon vibrator pivoted at its lower endl to theforwardly extending arm d bell crank lever is connected by a forward] extending link e to the u right arm f of a be l crank lever pivoted in tFe center/of` the machine at f/ and to the forwardly extending arm f 2 of which'there is pivoted, as in Figs. 1, 2, 5, 6 and 7, a plate or block g above which lies the ordinary universal bar h. The block g has two 'surfaces fdiierent radius or elevationfethat of greatest elevation bein marked g and the other g2,-and is ca able'o being so held that either of these sur aces, as will appear particularly from Figs. 5'and mayy lie directly below the universal bar and in line with the pivot g? of the block.` When.

eoy

The downwardly extending arm d? of this ment will be imparted to the ribbon vibrator and it should be such that printing will be p effected from )the top zone of tbe ribbon. When the block is moved to thc position shown in Fig. 7 it will not be engaged by the universal bar and there will be no movement of the lever f and consequently the ribbon vibrator wi l remain in normal position with `all parts of the ribbon below the printing oint, or out of range of the type. The block g may be conveniently adjusted and controlled by forming it with an extension g4, projecting below its ivot; and connecting that extension with t e rear end of a link i, the front end of which is connected with the lower end of a vertically disposed lever i pivoted on a horizontal axis i2 and having its upper end equipped-with a finger piece by which the lever ma be rocked lon itudinally of the machine.

t the 4side of t e lever is 110 knobs.

an outwardly projecting pin 'i3 adapted to engage either 'of the marked "Top, .ottom, Stencil in Fig. 11. To provide for extensibility of the lever to permit ready engagement and disengagement with such apertures, it is formed in two parta-that marked i. and that marked is, the latter being tted upon the upper part t" to slide thereon and the twobeing connected by a coiled'spring i".

positive sto rearwardly rear end lof which is connected the lower end of-al vertically in the' end of the part d2 extending down from the shift rail. The `upper end of -this lever is provided with a lateral pin 7'3 that extends over the forwardly projectin arm d of the ribbon vibrator,` operating bel crank The upper edge of this arm is appropriately recessed or notchedand the pin j@ arranged in such relation thereto that it will positively arrest the ribbon vibrator in its Vupward movement which is determined by the :before described adjustment of block g--thev lever i beingcoincidently adjustedbyme'ans of the 'nk j. As indicated in Figs. 9 and 10,'the bearing an. adjustable eccentric screw 7c., This will aord avery delicate and positive adjustment of the surfaces of the block with reference to the universal bar.

In Fig. 13, the ribbon vibrator adjusting lblock is indicated as 'a-' projection gs from a revoluble shaft m and 1s provided as before with surfaces g, g2 of diiierent radius or elevation. The shaft m (Fig. 14) may extend transversely ofthe machine and through the side plates thereof and be provided with The part g5 is held with sufficient Eositiveness in the position to which it may e adjusted by a detent spring m adapted tov engage a series of notches m2- in the lower face of the block.

In Fig. 15, the block having surfaces of different elevation engaged by the universal bar is marked g and is mounted to slide upon the forwardly extending arm f2 of the bell crank lever, being slotted at g7 and guided by ytwo headed screw bolts g8, g". -It may be adjusted by the link i in the same manner in :which the rocking block -g is operated. The bottom edge of the sliding block g6 is engaged by a detent b ook ma be afforded by making the guiding screw bo t g eccentricas indicated in the sectional view, Fig. 8.

This application-relates vto special adjustable ribbon .vibratoractua'ting means acting, according to the adjustment part to the vibrator different extents of movement when the universal bar is deapertures `8, 1907.
